摘要/Abstract

摘要： 对加工误差进行有效控制是弧面凸轮非等径廓面加工获得高精度和高效率的重要手段。根据空间啮合原理和旋转变换张量法,对刀具与凸轮的接触线进行分析,计算出加工过程中的刀位偏移量和偏移方向,进而建立了非等径加工弧面凸轮的实际工作廓面方程。运用微分几何原理推导出弧面凸轮廓面法向误差的计算方法,进行了非等径加工理论加工误差与仿真实验的对比,结果验证了该新的刀位控制技术对误差补偿的有效性。

Abstract: The effective control for the machining error is an important means for obtaining high precision and high efficiency of the unequal diameter profile machining of the arc surface cam. According to the space meshing principle and the rotation transformation tensor method, the contact line between the tool and the cam is analyzed; the cutter position offset and direction in the machining process are calculated. The actual working profile of the unequal diameter machining cam equation is established. Calculation method of normal error of globoid cam profile is deduced by the principle of differential geometry. The comparison between the machining error of the unequal diameter machining and the simulation experiment is carried out. The results verify the effectiveness of the new tool position control technique in error compensation.

Key words: arc surface cam, unequal diameter machining, error compensation, normal error, error control
